Abstract:

Objective To observe the characteristics and possible relevant factors of residual dizzy symptoms in patients with benign paroxysmal positional vertigo (BPPV) after successful particle repositioning maneuver. Methods The clinical characteristics of 486 patients with BPPV were retrospectively analysed. Patients were followed up for 3 months after successful particle repositioning maneuver, the characteristics and duration of BPPV of residual dizzy symptoms were observed, and the relevant factors were analysed. Results Among the 486 patients, 167(34.4%) were males and 319 (65.6%) were females, with the mean age of (56.9±12.9) years and mean disease duration of (9.1±8.4) d. Two hundred and eight-one patients (57.8%) had residual dizzy symptoms after successful particle repositioning maneuver, and the symptoms lasted for (27.27±23.32) d (2 to 90 d). The factors of female gender, longer disease duration and number of repositioning therapy ≥3 were significantly associated with residual dizzy symptoms. Conclusion Prompt diagnosis and effective particle repositioning maneuver can reduce the incidence of residual dizzy symptoms in patients with BPPV.
